Eaton TPN-35 Telecommunication Fuse - 170 Vdc, 100 kAIC
Part Number: TPN-35
Quick Summary
Eaton TPN-35 telecommunication fuse provides fast-acting overcurrent protection for telecom power systems. When protection is inconsistent or slow, outages ripple through networks and damage sensitive equipment. Note that formal certifications are not listed in the provided data; verify CE, UL, or IEC requirements with the supplier to ensure compliance in your region. The device offers a 35 A amperage rating, a 100 kAIC interrupt rating, and a 170 Vdc maximum voltage, all in a compact ferrule-end package. With current-limiting performance and non-indicating operation, technicians gain visibility where it matters most while maintenance cycles stay predictable and downtime remains minimized. This fuse supports high-reliability telecom installations and scalable protection strategies.

Eaton Specification Sheet - TPN-35
Feature: 35 A amperage rating, 100 kAIC interrupt rating, and a 170 Vdc voltage rating provide robust protection for telecom power rails. Business impact: fast fault clearance minimizes downstream damage and reduces unplanned downtime. Application: ideal for network cards, line cards, and rack power distribution in telecom enclosures. Feature: Current-limiting performance reduces let-through energy, protecting downstream electronics from surge and short-circuit events. Business impact: lowers component wear, extends equipment life, and reduces spare part costs. Application: critical paths in data-center interconnects and carrier-grade switching gear. Feature: Ferrule-end x ferrule-end connections with silver-plated terminals enable reliable, corrosion-resistant terminations. Business impact: smoother installations, lower contact resistance, and longer service life in challenging environments. Application: field-terminated assemblies in compact telecom panels. Feature: Non-indicating fuse with a compact form factor fits tight enclosures and simplifies mounting. Business impact: reduces layout changes and maintenance overhead while preserving clear fault isolation. Application: concealed or remote protection zones in telecom racks. Feature: Standard packaging and compact dimensions (0.76 in W, 0.76 in D, 3 in H) support easy integration with existing Eaton protection architectures. Business impact: faster procurement, consistent compatibility with ferrule-based terminations, and scalable deployment across multiple frames. Application: modular protection schemes in telecom and data-center facilities.

FAQs
The TPN-35 uses ferrule-end x ferrule-end connections and silver-plated terminals, which align with standard ferrule crimings. This enables straightforward, vibration-resistant terminations in panel-mounted telecom enclosures and minimizes termination variability during installation.
TPN-35 provides a 35 A amperage rating, 170 Vdc voltage rating, and a 100 kAIC interrupt rating. These specs translate to solid overload protection for telecom power rails, rapid fault clearing to limit damage, and compatibility with typical carrier-grade distribution environments.
The data specifies a compact ferrule-end design with high interrupt rating, which suits telecom racks and data-center interconnects. However, no environmental or IP rating is listed, so confirm weather exposure and enclosure protection requirements with Eaton prior to outdoor deployment.
Formal certifications are not listed in the provided data. To meet regional regulatory requirements, verify CE, UL, IEC, or other industry certifications with the supplier or Eaton’s documentation before procurement.
The fuse’s current-limiting action reduces fault energy and downstream damage, lowering spare-part costs and downtime. Its non-indicating design minimizes routine checks, while ferrule-term compatibility speeds installation, delivering a favorable total-cost-of-ownership in protected telecom infrastructure.
